CHEM 1410 Lecture Notes - Lecture 1: Copper(Ii) Sulfate, Zinc Chloride, Hydrochloric Acid
Document Summary
Objective: to identify whether or not or not a chemical change has occurred by observing evidence of that change with each potential reaction . In addition to this, one will observe examples of chemical reactions and will classify each of them into one of the four types of categories (synthesis, decomposition, single replacement, or double. Equipment: goggles and apron, burner and striker, forceps, spatula, wood splints. See handout types of chemical reactions lab provided by instructor for procedural guidelines. Initially the copper wire was brown and had a very shiny luster; upon heating and orange flame was produced that periodically sparked and eventually presented a green glow. Tangibly, the copper wire turned black and essentially disintegrated after entire heating duration. Before heating the copper (ii) carbonate placed into the test tube had a green semblance and was in a loose (not dense) state.
